A series of bright fringes appears on the viewing screen of a Young's double-slit experiment. Suppose you move from one bright fringe to the next one farther out from the central bright fringe. Does the difference in path lengths of the light waves increase or decrease, and by what amount does it change? Express your answer in terms of the wavelength λ of the light.

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !
